iPhone alarm bug leads to UK lie-in

iPhone

It must be the most welcome flaw to hit an Apple product, as a bug in iPhone alarm settings gave many across Europe an extra hour's sleep this morning.

When Britain flipped out of summer time and back to GMT over the weekend, the iPhone's clock automatically made the change - but didn't update alarm settings, leaving some users asleep for an extra hour.

This morning, Twitter was awash with complaints. "Anyone else's iPhone alarm delayed by an hour? Great start to a Monday, cheers Jobs," said one.

"Don't trust your iPhone alarms folks. They're going off one hour late since clocks changed," noted another user.

As Engadget has noted, the bug was first noticed in New Zealand and then a week later in Australia, with users woken up an hour early for the area's hour jump forward last month.

A month ago, a New Zealand user on the Apple forum noted: "I guess we're just lucky this didn't occur when the clock went the other way."

The iOS4 bug can apparently be avoided by using one-off alarms, rather than pre-set regular wake-up calls.

Since then, Apple clearly hasn't fixed the bug or chosen to alert European customers. The company wasn't available for comment at the time of publishing.

Possibly nobbled themselves

'The company wasn't available for comment at the time of publishing.'

Probably because they have all overslept.:-)

Grrrr!

I use Alarm Clock Pro and it woke me up an hour early this morning! I had the option of starting a productive day one hour earlier or getting my head down for another hour ... no contest!

I think it's next weekend that the US goes back. So it must be something else that's made them dopey.

I wonder if they'll dare not to say or do something for their home market. Hmmm...

why can't it just go by the time on the main clock? My alarm still read the same. The clock had changed correctly. Doesn't make sense

Erm... I've made the switch to WP7, it woke me up on time. Damn. What better excuse could there have been to turn up late for work. :(

how is WP7?

Apparently this bug will be fixed in 4.2 For now I have had to set my alarm 1 hour earlier.

So how would it work if I went to the US and relied on my iPhone (which I don't own) to wake me at 7 a.m., the same time as the UK - would it continue to wake me at 07:00 UK time even after I reset the time / time-zone?

Seems a curious way to program it, using the central time not local. Maybe I'm missing something.

Fortunately I use an alarm clock (yes, and a watch!)

4.2 this week then?

If it is fixed in 4.2, and 4.2 is due out in November, and the US changes next weekend, the best time would be the usual Tuesday release tomorrow...

Android

Android didn't seem to struggle with this rather simple task.

Android always gives a pop-up of the time left till the alarm and it managed to do the simple maths!

Oh well, maybe the iPhone 5 might solve this along with the signal and unlock issues.

By adin2001uk on 1 Nov 2010

James016 are you saying that it still won't work even now I've deleted all my alarms and reset?
I've never had this problem before so I'm assuming they introduced this bug in the last update

By TimoGunt on 1 Nov 2010

worked ok for me

i have 4.0 on my ipod touch and the alarm worked fine for me, as did the clock automatically setting itself back an hour

By fernsie on 1 Nov 2010

Android problem too

My Galaxy S suffered from this- 6am alarm even though the clock was set correctly. However when I cancelled the alarm then re-set it, it went off at 7am as it was supposed to.

By Flangie on 1 Nov 2010

@TimoGunt. That's correct. Deleting and adding new alarms does nothing. The bug affects recurring alarms only. The only way round is to set a recurring alarm 1 hour earlier or set a single alarm every day.

Info on the bug

I found that if you set a recuring alarm say monday tuesday wednesday thursday and friday like most of us do for work the it goes off an hour late. If you set the alarm to go off every day including saturday and sunday then it works fine.

Info on the bug

Also if you set the alarm to go off at say 9:00 on Monday then it is late aswell.
If you dont state a day it also works fine

Is it a bug?

I'm unsure if this is a bug, me and my partner both have iPhones... and we set a third alarm just incase because all the talk over the alarm not working during time changes.. however both our phones woke us up at the right time with the hour deference too.... so no issues here worked like it should....this will cause apple more problems as some do and some don't ;-)

By chriscuk18 on 1 Nov 2010

It's definitely a bug. I can tell you for a fact that if you have the alarm set for weekdays then it will go off an hour late. I'd love to know the code for this so that I can understand the logic behind not looking at the phone's clock.
